Trump’s pick to run US cyber agency CISA asks to drop out

Trump’s twice-chosen pick to run the U.S. federal cybersecurity agency CISA has requested to withdraw from the position, leaving the agency without any clear person to lead it on a permanent basis.

In a letter to the White House on Wednesday, Sean Plankey requested that the Trump administration withdraw his nomination, citing a holdup in the Senate, which is required to hold a vote to approve his appointment.
